Finding the right inductance value—and peak current rating—for your SMPS converter can be a bit of a hassle. So here’s a little tool to help you! Simply use this calculator, which’ll calculate all the parameters you need to factor in. The calculator supports the common, simple topologies: Boost (step-up), Buck (step-down) and Buck-boost (inversion – positive to negative).
Input values | Output values |

For prefixes, use scientific notation.
SI prefixes and the associated exponents are:
nano: e-9
For instance, 100 mA should be written as 100e-3 in the input field. |
